Question

I have a RelativeLayout in which i have one ImageButton.
I need the position parametres of this item and I don,t know how to get them.

I have try with:

ImageButton user = (ImageButton) findViewById(R.id.User);
int x =user.getTop();
int y =user.getLeft();

But the result is allways 0;

Thank you.

I think you are invoking this method when the layout is being drawn, instead you should use:

ViewTreeObserver observer = user.getViewTreeObserver();
observer.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        //in here, place the code that requires you to know the dimensions.
        //Place your code here
    }
}
